AUTOMATIC VALVE AND RIM.

Specification of Letters Patent.

Application filed MarchS, 1918. Serial No. 221,185.

To all whom it may concern:

Be it known that I, HARRY B. EADs, citizen of the United States ofAmerica, residing at Vicksburg, in the county of Warren and State ofMississippi, have invented new and useful Improvements in AutomaticValves and Rims, of which the following is a specification.

This invention has reference generally to improvements in valves andmore particularly relates to an automatic valve and rim.

It is the principal aim and object of this invention to provide a deviceof the above character designed to act in the capacity of a check whenused in conjunction with suitable pumping apparatus for controlling theflow of liquids while suitable resilient means also acts in connectionwith the pumping means for reseating the valve.

As an additional object the invention embraces the provision of a deviceof the above mentioned character wherein the rim employed is of a novelform and operates with the valve body for protecting the latter duringoperation so as to increase the longevity thereof.

It is a more specific object of this invention to provide a device ofthe above mentioned character wherein the valve casing is designed toform a seat for the rim while in addition Suitable guiding means isprovided with the rim and designed to co-act with the casing in guidingthe movement of the valve body and rim.

As a further improvement the present invention includes the provision ofimproved means for governing the tension of the resilient means.

Among the other aims and objects of this invention may be recited theprovision of a device of the character described with a view tocompactness, and in which the number of parts are few, the constructionsimple and the hcost of production low and the efliciency hi Otherimprovements and novel details in the construction and arrangement ofthe various parts of the apparatus Will be brought out more in detail inthe description to follow, which for a clear understanding of theinvention hould be considered in connection with the accompanyingdrawings forming a part hereof, and wherein is disclosed for the purposeof illustration a convenient and satisfactory embodiment of theinvention. It is to be noted in this connection that minor changes inthe construction and arrangement of parts may be made without departingfrom the principle of operation of the various parts.

The invention is clearly illustrated in the accompanying drawings, inwhich t Figure 1 is a vertical section of the invenion.

Fig. 2 is a top plan view thereof.

Fig. 3 is a horizontal section taken on line 3-3 of F ig. 1, and

Fig. 4. is a detail ofanother form of the invention.

Similar characters of reference are employed inall of the abovedescribed views to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings there isprovided a valve embodying a tubular attaching casing 1 formedon the endWith an exterior annu- 2 the outer surface of which tolar flange getherwith the adjacent edge of thecasing constitute a valve seat 3. Alsoformed inte gral with the casing but internally thereof and near theseat is a spider 4 which bridges the casing. A boss 5 is formed at thejunc' ture of the arms and has the surface thereof flush with the seat 3and provided with an interiorly threaded socket 6 for a purpose thatwill presently appear. Likewise, a secondary seat 7 is provided on theouter surface of the arms of the spider between the outer edge of theboss and the inner edge of the casing.

The valve body 8 is of a disk like form and preferably is constructed ofrubber or a substitute therefor, being provided with a central opening 9and having the outer edge arranged in substantial alinement with thecasing when the inner surface of the body abuts the Seat 3.

In order to protect the valve body from the excessive pressure of waterwhen the a rim 10 is employed being of an annular form and constructeddesirably of metal and of such size that it may be snugly accommodatedon the secondary seat 7 beneath the valve body 8 as indicated in Fig. 1.Guides 11 project at right angles from the inner face of the rim nearthe outer edge thereof and lie against the inner surface of the casing 1so as to cooperate therewith in guiding the movement of the rim andvalve body.

As intimated improved means have been employed for yieldingly holdingthe valve valve is in use,

Patented Apr. 15 1919 i upper or outer body and rim seated. In reducingthis feature of the invention to practice a helical coil spring 12 isemployed and has one end bearing against the outer face of the valvebody while the opposite or outer end bears against the head 13 of a bolt14:. The inner end of the bolt is threaded as at 15 and adjustablyengaged in the threaded socket 6 so that when the head is adjusted thetension of the spring will be regulated to act correspondingly on thevalve body and the rim. Incidentally the bolt l l is arranged throughthe opening 9 in the body 8 so as to guide the movement of the body whenthe valve is .in operation.

In Fig. 4 there is disclosed a modified form of the invention whichconsists in the provision of two rims 16 with guides 17, similar inconstruction to the rim 10 and guide 11, respectively arranged on theopposite faces of a valve body 18 and connected thereto by rivets 19. Byemploying the two rims et cetera the valve body may be reversed.

The mode of operation of'the invention may be reviewed as follows: 7

Assuming that the parts have been assembled in the manner, described andas indicated in drawings particularlyFigs. 1 to 3, the action is thesame as a check valve. When pressure is exerted beneath the body 8 thelatter will rais together with the rim 10 against the tension of thespring while water will flow through the casing 1. In reseating, thetension of the spring 12 against the body after the pressure diminishesand reseats the valve body while the water under pressure acts as acushion for the rim 8 which lessens the chance of breaking the rim.

It is believed description that a further detailed description of theoperation ofthe invention is entirely unnecessary.

As many changes should be made in the 7 above construction and manyapparently widely different embodiments of this invention could be thescope thereof it is intended that all matter contained in the abovedescription or shown in the accompanying drawings shall be incopies ofthis patent may be obtained for five cents each, by addressing theWashington, I). 0.

7 terpreted as seat, a spider formed in view of the foregoing madewithout departing from.

illustrative and not in a limited sense. It is also to be understoodthat the language used in the following claims is intended to cover allthe generic and specific features of the invention herein described andall statements of the scope of the inven tion which as a matter oflanguage might be said to fall therebetween.

Having thus fully described'the invention what is claimed and desired tobe secured by Letters Patent is: V
